Prices & alerts
Where the numbers come from, and how the app can tell you a price moved without anyone learning what you own.
Screenshots are from the iPhone app. The Android app has the same features, drawn in Android's own style.
Where prices come from
The app fetches spot prices from our server, which relays them from a market data provider. The request asks for prices — that is all it contains. It carries no inventory, no holding, no total, and no identifier tied to you.
This is worth stating plainly because it is the usual place a "private" app leaks: our server can see that a device asked for the price of gold. It cannot see that you own any.
How often prices refresh
On launch, periodically while the app is open in front of you, and whenever you pull to refresh. The app does not poll in the background — a phone in your pocket is not talking to us.
Prices are cached, so the app is fully usable offline; you will see the last figures it retrieved, and the display tells you they are not live.
Charts and ranges
Tap a metal in the ticker for the full chart. The range pills are 1D, 7D, 30D, 90D, 1Y; the first three are free and the last two are part of Pro. One year is the maximum — we retain 365 days of history and no more.
Price alerts Pro
An alert is a rule: tell me when this metal, in this currency, crosses this price. Create them under More ▸ Price alerts. You can have up to ten active alerts, and the app will not let you create the same rule twice.
Alerts need notification permission. If you declined it at first launch, you can grant it later in your phone's system settings.
How an alert stays private
The push notification our server sends is empty — a wake-up with no content in it. Your phone wakes the app, the app looks at the price and at your rules, and your phone writes the sentence you read on the lock screen.
So the notification text never travels. Apple and Google carry an empty envelope; our server sends one. The only place your alert text exists is on your own device.
Limits
Ten active alerts. Pro only. Alerts are threshold crossings on spot price — not on your portfolio's total value, which would require telling the server what you own.
